摘要
结合某心墙堆石高坝所采用的坡残积砾石土心墙料,以大型击实试验和大型直剪试验为主要手段,揭示了随着大于5 mm的粗粒含量P5增加,砾石土的最大干密度增加,抗剪强度指标C值减小,φ值增大的规律,并通过回归分析得到了它们之间的关系,为该类坡残积砾石土的应用提供了参考依据。
Combining with the used slope residual gravel soil core wall material of a core wall high rockfill dam,taking large-scale compaction test and large direct shear test as the main means,revealled with the increase of coarse grain content P5 than 5 mm,the maximum dry density increased of gravel soil,the shear resistance strength index C value decreased,the φ value increased,and through the regression analysis obtained the relationship between them,provided reference for the application of this kind of slope residual gravel soil.
